Hi.
I was just testing LVM2 on kernel 2.4.20 + 2.4.20-dm-7. I was trying to grow
a filesystem online. I wanted to lvextend then resize_reiserfs to make more
room for a potentially full FS; but it looks like LVM2 (or dm) isn't working
under load, or with a big full disk cache or such.
But LVM hangs after it prints "Extending Logical volume ..." and I can no
longer use the block device for any purpose, although the rest of the system
is fine.
I've included a log to demonstrate everything that I think might be important.
I'd be happy to help if somebody has more questions. Hopefully I just forgot
a kernel patch or something.
BTW, I just tried this on a single disk (no raid) and I got the same result.
Likewise with a the kernel + VFS lock patch.
Thanks much for any input.
